SetCalc is a musical set-class calculator that calculates the set class as you type in pitch classes by either letter name or number. The webapp is designed to be used with some sort of touch screen device, such as iPhone, iPod Touch, iPad, etc.

Click on image to open SetCalc.

Once you have entered the set, you can find out more details by hitting the “More Info” button on the top right. This opens up a page that gives the Tn and TnI classes of the set, the M5-related set, the complement, and the interval vector.

The webapp is written entirely in html and javascript, which means that you can continue to use it while offline. On the iPhone, you can hit “Save to Homescreen” from the Bookmarks menu and an icon will appear as if it were a regular iPhone app.

Let me know if you have any suggestions for improvement, and any other comments.
